Roy Surname

Roy Surname

I have just began my search, with very little info to go on! All i have is my Dad's Name and birth date! I know his family was all from New Brunswick. Looking for any relatives from the area to help with my search! Father James (Jimmy) Roy born June 20th 1946 in Bathurst or Blackville NB, his Father ? perhaps Douglas Roy? Not sure where to start with such little info, I believe they could be French/Native?
